Re: Woes trying to get to grips with new-fangled stuff (SOLVED!)

[Cruithne3753]

After a bit of a break from programming, I have started a new FPS-type project going.  Was making nice headway, able to walk around a simple scene made of several areas with basic portal entity culling (rather pleased with myself for managing to work that out).  It then came to my attention that the code I was using (glBegin()/glEnd() stuff) is now old hat, I should be using these VBO and shader thingies instead.  It feels like I've been kicked down several flights of stairs... ouch.  

So I have to start over, trying to compile example code (TheQuadColoredExample), but it won't compile, just throws up a load of this:-

I'm using LWJGL 2.8.5, the jar files are dated 04/11/2012 (or 11/04/2012 if you're American!), JDK is 1.6.0_24... I'm sure this should be pretty up to date, how come there are different sets of function call parameters??!!

Thanks

I would double-check that you are using the version of LWJGL that you think you are using. The overloads for glGenBuffers, etc. were added a while ago (way before 2.8.5).

(Slaps head!)   Just realised I had a folder with LWJGL source code extracted to it which had been there a couple of years, it was shadowing the JARS!  Deleted it, it now compiles and runs!

Thanks for that pointer!
